STARTING MECHANISM FOR MANIFOLDING DEVICES.

Application filed September 5, 1925. Serial No. 54,617.

The present invention relates to restarting mechanism for autographic registers or the like, particularly of the. type wherein the restartin wheel is connected with the shaft on which it is mounted by triction clutch, so that the restarting wheel may remain idle during part of its rotation. A device of this type is shown in my co-pending application, Ser. No. 506,291, filed October 8, 1921. For the purposes of illustration, I show the present lnvent on applied to the mechanism set forth in. sa d earlier application to which reference s made for a more complete showing of various parts of the machme.

When the restarting wheel is held by trlction engagement with the driving shaft on which it is mounted, it sometimes happens that the friction is too slight to cause this wheel to operate. The present invention relates particularly to a method of overcom ing' these diiiiculties. 0

in the accompanying drawings which show an illustrative example or my present invention as applied to the structure she in my said earlier application, Ser No. 506,291, Fig. 1 shows the various parts in the position which they occupy when the restarting wheel is held stationary; Fig, 2 shows the parts at the time that restarting leagues, and Fl 3 is a perspectiveshowin the details oi: the novel structure covered, hy the present application.

For the purposes of simplicity, parts that are common to the present application and to the said earlier application, are given the same reference letters as are applied in the earlier application. Attention is particu= larly called to Fig, t of the earlier application.

Numeral 39 designates a lead roller under which pass the aper strips 9. Beneath the roller 39 is a att it, loosely monnted on which is an auxiliary roller 5U. the sides of the roller 50, attachedxto shalt all, are two collars 4'2.- Roller so is heldin position with relation to one collar 4;? by a spacing sleeve 5i. Between the roller and the other collar l? is a compressed coil spring as, tendency at the auxiliary roller 50 to revolve with the shaft 44 due to friction- The auxiliary roller 50, in the form here shown, is made'u of a plurality of disk-like laminations loc ed togather by pins, and its general conformation is cylindrical. One surface of the roller is however flattened at 50*; and diametrically opposite this fiat surface, a recess 50 is cut in one end of the rollerto coact with a restraining pawl 62. Under normal conditions the feed roller 39 will engage with roller 50 except when the flattened surface 50 is presented to the feed roller.

Roller 50 is normally held against, rotation with shaft (it, due to the fact that pawl 62 is in engagement with recess 50. However, when pawl 62is moved out of recess 50", roller 50 will turn with shaft 44 and will cause the paper stri s 9 to advance. lip to this point the mec anism described is the same as that shown in my earlier application.

in order to insure the operation of roller 50, shaft it carries a toothed portion 100 which is embraced between the sides of the roller 50. A small toothed roller 102 is loosely mounted on a pin 104 in such a way that this roller can engage with the tooth 100 on shaft t l, but can move out of such engagement, The roller 102 is positioned ad acent one edge of the hat portion 50 ot rol or 50.

When the roller 50 is held from rotation h pawl 82,- roller 102 can remain idle.

-owevor, after the release of awl d2, as roller 50 advances towards t e position shownin Fig, 2, roller 1M2 will enage with the paper sheets 9 and will be had in engagement with teeth 100. are nppermost on roller 102, due to the fact The teeth that lit that they have engaged with the pa er strips, will tend to remain stationary, bat the operation oi shalt at will rotate roller lOiZ, causing it to move roller 39. This movent or roller 102, acting through pin the, will assist to draw circular portion of roller 59 tinder roller 39. As soon as roller 16% passes out :lrom agement with the paper roller to wi' serve to cause sheets advance.

What I claim is:

1. In combination, a roller, a shaft adjacent the roller, a member having a portion of its circumference adapted to cooperatewith the roller mounted on said shaft, friction mechanism connecting said shaft. and said member, and means carried by said member adapted to supplement said friction mechanism to cause said member to more into coo ration with the roller.

2. A evice as characterized in claim 1, in which said means comprises a supplemental toothed roller carried by said member, and adapted to be rotated by engagement with said shaft.
